Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to drawing inset.

Jack the vehicle up until the wheel you are
changing is raised from the ground.

Mounting a wheel

Unscrew the lug bolts and remove the
wheel.

Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Clean the lug bolts.

Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes. When you
mount wheels other than Genuine BMW
light-alloy wheels, different lug bolts may
also be required.

Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.

Lower the jack and remove it from beneath
the vehicle.

After mounting

Tighten the lug bolts in a diagonal pattern.

To ensure safety, always have the lug
bolts checked with a calibrated

torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
101 lb ft/140 Nm.

Stow the defective wheel in the cargo area.

Check and correct the tire inflation pressure
at the earliest opportunity.

Protect valve stems and valve stem
seal caps from dirt and contamina-

tion. Dirt in valve stems is a frequent source
of gradual air loss.

Reinitialize the Flat Tire Monitor

or reset

the Tire Pressure Monitor

, refer to

pages

Do not initialize the Flat Tire Monitor
when driving with a compact wheel.

Replace the damaged tire with a new one as
soon as possible and have the new wheel
balanced.

Driving with compact wheel

Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not deacti-

vate DSC; otherwise, unstable driving condi-
tions may result.

Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.

Only one compact wheel may be
mounted. You should re-equip with

wheels and tires of the original size as quickly as
possible.

Vehicle battery

Maintenance

The battery is 100% maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.

Warning lamp

The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-

function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.
